Consult Analog Devices Military Databook for details. 2 Relative Accuracy is defined as the deviation of the code transition points from the ideal transfer point on a straight line from the offset to the full scale of the device. See Measuring Offset Error. 3 Operation of the 0 volt to 10 volt output range requires a minimum supply voltage of +11.4 volts. 4 Passive pull-down resistance is 2 k for 2.56 volt range, 10 k for 10 volt range. 5 Settling time is specified for a positive-going full-scale step to 1/2 LSB. Negative-going steps to zero are slower, but can be improved with an external pull-down. 6 The full range output voltage for the 2.56 range is 2.55 V and is guaranteed with a +5 V supply, for the 10 V range, it is 9.960 V guaranteed with a +15 V supply. 7 A monotonic converter has a maximum differential linearity error of 1 LSB. 8 See Figure 7.
